Merging flux emergence simulations analysis with observations
A. Ortiz, J. Martinez-Sykora, V.H. Hansteen


We analyze quasi-realistic 3D numerical simulations of magnetic flux tube emergence in a computational domain spanning the upper layers of the convection zone up to the lower corona and compare them to
observations made within the same span. The aim is to study the response of the solar atmosphere and of the pre-existing magnetic field to the rising flux tube, combining and comparing observations and simulations. We will synthesize continuum images at different wavelengths, as well as synthetic Ca II H line images and velocity field distributions, in a similar way to our observations. Our goal is to describe the emergence of a magnetic flux tube into such an atmosphere and we will show how the different diagnostics are formed as a result of this emergence.
